“…Among the possible ethnomedicinal uses of E. graminea include treatment of skin infections such as ulcers, cancers, tumours, warts, and other diseases as practiced by Colombian traditional healers . It has also been reported to be poisonous to ruminants 5,6 . In Nigeria, the plant has not been specifically indicated for the treatment of many disease condition.…”

Background: Euphorbia graminea Jacq. (Euphorbiaceae) is a medicinal plant with limited information on its biological applications and reported scientific studies. Method:in vitro This work was aimed at investigating the antiproliferative and antioxidant effects of leaf the extract and fractions of by employing the Sulforhodamine-B as well as the E.graminea DPPH-RSA (2, 2-diphenyl-1-picrylhydrazyl) assays respectively. The extract and fractions of E. graminea displayed growth inhibitory and cytotoxic effects in a concentration dependent manner on the cell lines.Results: At 250 µg/ mL, the extract recorded -3.1 and +75 % cytotoxic and growth inhibitory effects on MCF-7 and NCI-H460 cell lines. While the cytotoxic effect became more pronounced on MCF-7 cell lines as -2.19 and -9.6 % cytotoxicities were recorded by the chloroform fraction at 75 and 100 µg/ mL the ethyl acetate fraction recorded +58.72 and +89.33 % inhibitory effects at similar concentrations. The hexane and ethyl acetate fractions were inactive against NCI-H460 cell lines at all concentrations. The antioxidant activities further corroborated the antiproliferative activities as IC of 58.88 µg/mL was recorded by the chloroform fraction against 46.77 µg/mL by Quercetin. 50 Conclusion: This work has shown that the antiproliferative and antioxidant activities of E.graminea resides more in the chloroform phase and could be due to the active metabolites it contained. In continuation of this work, the Isolation and characterization of some of these metabolites will thus be carried out.

A gall midge, Prodiplosis hirsuta Kolesik sp. nov., is described whose larvae feed on shoot tips of Jatropha gossypiifolia and Jatropha clavuligera in Paraguay and Bolivia. Morphology and the mitochondrial COI gene sequence of the new species are given. Field survey and preliminary no‐choice host specificity tests showed that the host plant range of P. hirsuta is confined to J. gossypiifolia and J. clavuligera. The apparent host specificity and the damage potential make P. hirsuta a prospective candidate for biological control of J. gossypiifolia in Australia.
